Material processing, rangefinding, laser target designation, surgery, tattoo removal, hair removal, research, pumping other lasers (combined with frequency doubling to produce a green 532 nm beam). One of the most common high-power lasers.
A laser weapon [2] is a type of directed-energy weapon that uses lasers to inflict damage. Whether they will be deployed as practical, high-performance military weapons remains to be seen. [3] [4] One of the major issues with laser weapons is atmospheric thermal blooming, which is still largely unsolved.
A green laser pointer is a frequency doubled Nd:YVO 4 diode-pumped solid state laser . Nd:YAG can be also made to lase at its non-principal wavelength. The line at 946 nm is typically employed in "blue laser pointer" DPSS lasers, where it is doubled to 473 nm.
Powerful laser is 'brightest light in the universe'—The world's most powerful laser as of 2008 might create supernova-like shock waves and possibly even antimatter " Laser Fundamentals " an online course by F. Balembois and S. Forget.
Patrick Murphy, editor of LaserPointerSafety.com, said green lasers are the most widely available and are also brighter to the eye than a red or blue light of the same power.
Green DPSSLs are usually around 20% efficient, although some lasers can reach up to 35% efficiency. In other words, a green DPSSL using a 2.5 W pump diode would be expected to output around 500-900 mW of 532 nm light. In optimal conditions, Nd:YVO 4 has a conversion efficiency of 60%, while KTP has a conversion efficiency of 80%.
